Their fairytale has finally come true: Couple finish building a castle in their garden. . . after 37 YEARS

Eventually, it was a fairytale finish for one German couple who after 37 years, finally completed building a castle in their backyard.

The fortress, which is made of stone, bricks and cement, started its life as a wall, but over the years Heinz and Hildegard Schönewolf, from Dudweiler, Germany began adding to it - in some style.

However their dedication came at a price, and the couple have never had chance for a holiday since the project began back in 1975.

Dedicated craftsman Heinz has said he will never be full satisfied with his work of art as he believes there are always going to be improvements that can be made.

But he has opened it up for the public to enjoy, free of charge.

The Schönewolfs estimate they have spent over £40,000 building the castle, which is 15-metres high and 15-metres wide and features towers, battlements, narrow pathways, a charming Rapunzel room and even an 18,000 litre aquarium in the basement.
